It’s cool though, cause it’s not really a street anyways. Item 11 of the January 19th meeting for the Philadelphia City Planning Commissions shows:
Streets Bill No. 090924: Authorizing the striking and vacating the legally open portions of Adams Avenue from Aramingo Avenue to the northwesterly right-of-way line of the Delaware Expressway and reserving and placing on the City Plan a right-of-way for drainage purposes within a portion of Adams Avenue being stricken (Introduced by Councilmember Krajewski on December 17, 2009; Presented by William Erickson).
This is my interpretation of the section in question:
It’d be cool if they were strickening and doing draining for development but I get the impression it’s just for city map house cleaning seeing that it’s all under highway.
